Not AFAIK, but Amazon's been selling Graviton 1 to Microtik.
But, those are really old generation parts given there are a number of A76 based systems appearing on the market. Those chips are a giant step above the A72 based machines the same way the A72 is a big step above the A5x ones. (aka its a gravaton1->gravaton2 kind of step, or the diff between atom and the mainstream i5/7 parts)
Edit: Notice the G1->G2 uplift in single threaded perf. https://www.anandtech.com/show/15578/cloud-clash-amazon-grav...
That is going to be the uplift going from a A72->A76+ platform. The IPC is nearly 2x, and translates to going from a early 2000s era x86 to something fairly modern.
